1.6 L Waterproof Frame Bag

The RockBros top tube bag offers 1.6 litres of storage in a slim, waterproof shell that mounts to the front frame of MTB, road or city bikes. It is built for cyclists who want phone, tools, nutrition and small essentials within easy reach without a bulky pack.

Three-Layer Shell and Sealed Zipper

A construction of 840D nylon, internal PP board and TPU coating combined with an adhesive waterproof zipper keeps rain and splashes out of the main compartment. Stiff sidewalls hold the bag shape so contents stay organised and the profile stays narrow against the frame.

Check Phone Size and Strap Version

The bag fits phones up to 6.8 inches; larger devices will not close properly. Mounting uses adjustable hook-and-loop straps that suit a range of top-tube diameters, but very oversize or unusually shaped tubes may not secure firmly. Stock ships with either original or updated straps; both meet the same specification.

Questions about this item

How long will the hook-and-loop straps last before they need replacing?

The straps are an upgraded adjustable hook-and-loop design that fits most MTB and road frames; they can be swapped out by the rider if the grip weakens after extended use

What limits how much gear I can carry on long rides?

The bag is rated at 1.6 L capacity and a 1 kg load limit, so volume and weight are the first constraints on extended trips

Does the bag trap heat against the frame during all-day riding?

The slim 8.48 × 3.35 × 2.16 in profile and polyester construction keep it clear of the legs, allowing airflow around the frame tube
